RAILWAY-JOINT. 7

To all whom it may concern."

Be it known that I, BYRON ELLswoR'rH CARL, a citizen of the UnitedStates, residing at New York city, in the county of New York and Stateof New" York, have invented certain new and useful Improvements inRailway-Jointsyand I do hereby declare the following to be a full,clear,,and exact de-- scription of the invention, such a's'will enableothers skilled in the art to which it appertains to makeand use thesame.

. My invention relates toimproveinents in -join'ts'for railways, and isintended to pro vide a strong, "rigid, simple, and. elfective joint,which will hold the abutting ends of the rails against verticaln ovementduring the passage of the rolling stock over the same, and yet whichwill permit the necessary longitudinal play of the rails, incident toexpansion andcontracti'on, due to tions in temperature; 1

* My invention will be understood by reference to theaccompanying"drawings, in which the same parts are indicated by the sameletters throughoutthe several views.

Figure 1 is a side elevation, showing the variacomplete rail joint.vFig. 2 shows a section along the line 22 of Fig. 1, and looking I inthedirection of the arrows, parts being shown in elevation. Fig. 3 showsa section along the line 3'3 of Fig. 1, and looking down, parts beingshown in elevation; and Fig. 4 is a similar view to Fig. 2, but shows amodification, in which the supporting block passes through the fishplates.

Referring first to Figs. 1, 2, and 3, the rail 1 is provided with theusual shoulders 2,

beneath the head thereof, and with the usual flanges 3 and web 4,connecting the head and base of the rail. At each side of the web arefish plates, 5, provided with faces 6, adapted to engage the shoulders 2beneath the head of the rail, and with flanged bases 7 and downwardlyprojecting ends 8, to engage the flanges 3 at the base of the rail. Thefish plates are held together by'bolts 9 and nuts 10, beneath which nutsare washers 11, preferably of the form usually designed to pre ventturning of the nuts. i

The web of the abutting ends o'f the" rail iscut away to receive theelliptical block 12, and to provide a slight clearance between the endsof said block and the ends of the elliptical slot in the web, so thatprovision may be had for the expansion and contraction of the rail."This block 12 is substanj Specification of Letters Patent. ApplicationfiIed'April 11, .1912. 7 Serial No. 690,082.

elliptical, having arch-shaped ends and a flat main body portion,asshown in dotted lines in Fig.1. At each side,this

block 12 is provided with tapered wedge faces 13, to engage incorresponding sockets 14;, formed in the inner'side of the fish-plates I5. .These sockets 14 may extendonly partly through the fish plates, themetal being pressed outward, as at 15, as shown in Figs. 1, 2, and 8; orthe metal may be punched through entirely, as shown at 16 in Fig. 4.-The bolts. 9 being at either side of the supporting block 12, setting upof the nuts 10 s will cause the sockets 14 in thefishplates to engagethe wedge faces 13 of the block 12.

To form. a stiff, tight joint, the block 12 wlll support the free endsof the abutting ralls, and will transmit any vertical strains on the topof the rail to the fish plates, and

to the abutting rail; and the result will be a firm, rigid, andefficient joint.

It will be obvious that various modifications might be made in theherein described apparatus, and in the construction, combination, andarrangement of parts, which could be used without departing from thespirit of my invention. i

Havingthus described my invention, what I claim and desire to secure byLetters Patent of the United States is 1. In a railway joint, thecombination with a pair of fish plates each provided with an ellipticaltapered socket on the inner face thereof, of anelliptical supportingblock provided with wedge faces at each edge adapt-edt-o engage in thetapered sockets,

and to pass through and fit in a recess in the webs of the abuttingrails, and means for clamping said fish plates together. and for forcingsaid wedge faces ofsaid blockinto said tapered sockets, substantially asdescribed.

2.111 a railway joint, the combination with a pair of fish plates eachprovided with an elliptical tapered socket on the inner face thereof, ofan elliptical supporting block provided with wedge faces at each edgeadapted to engage in the tapered sockets, and to pass through and fit ina recess in the webs of the abutting rails, bolts passing I through saidfish plates and through the webs of the rails,and nuts on said boltsfor" clamping said fish plates to the rails and for forcing said wedgefaces of the supportmg block into said tapered sockets, subs'taln tiallyas described.

3. In a railWay joint, the combination With a pair of rails each havinga semielliptical recess cut in the Web at the end thereof, of a pair offish plates each provided With an elliptical tapered socket on the innerface thereof, an elliptical supporting block provided With Wedge facesat each edge adapted to engage in the tapered sockets, the main body ofsaid block passing through said recesses in the Webs of the abuttingrails, and means for clamping said fish plates together and for forcingsaid Wedge faces of said block into said tapered sockets, substantiallyas described.

4. In a railway joint, the combination with a pair of rails each havinga semielliptical recess cut in the Web at the end thereof, of a pair offish plates each provided with an elliptical tapered socket on the innerface thereof, an elliptical supporting block provided With Wedge facesat each edge adapted to engage in the tapered sockets, the main body ofsaid block passing through said recesses in the Webs of the abuttingrails, and bolts passing through said fish plates and through the Websof the rails, with nuts on said bolts for clamping said fish plates tothe rails and for forcing said Wedge faces of the supporting block intosaid tapered sockets, substantially as described. a

In testimony Whereof,I afliX my signature, in presence of tWo Witnesses.
